Question

您好我的控制器中有以下操作

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Index()
{
    IEnumerable<SurveyResult> myresult = filterData();
    totalCount = myresult.Count<SurveyResult>();
    ViewBag.totalCount = totalCount;
    //myresult = myresult.Skip<SurveyResult>(100 * pageIndex).Take<SurveyResult>(100);
    return View(myresult);
}

这是我的观点

@model IEnumerable<SurveyResult>
@{
    ViewBag.Title = "Survey Results";
}
@using (Html.BeginForm())
{

    <table class="std-tbl">
        <thead>
            <tr>
                <th>
                    DEL
                </th>
                ...

                <th>
                </th>
            </tr>
        </thead>
        @Html.DisplayFor(x => x, new { pageIndex = ViewBag.index })
    </table>
}

我对SurveyResult有部分观点，但我不包括它，因为我认为它不相关。这是我的问题。上面的代码工作正常，但只要我取消注释以下行

myresult = myresult.Skip<SurveyResult>(100 * pageIndex).Take<SurveyResult>(100);

我得到“路径中的非法字符。”我认为它可以找到SurveyResult的partialView。我不明白为什么它可以在评论上面的行时找到它但是当它没有注释时却不能找到它？谢谢。

这是我的堆栈跟踪

Here is the source Error:

第161行：第162行： 第163行：@ Html.DisplayFor（x =＆gt; x，新{pageIndex = ViewBag.index}） 第164行：第165行：}

Answer 1

DisplayFor正在查找以EF生成的实现类名称命名的视图，其中包含非法字符。

尝试在控制器中调用.ToList()。

路径中的非法字符。使用Skip并使用IEnumerable时出错
